The flask API for mtlfs.vta.org

mtlfs_flask_server

This is a simple flask server meant to be an API for the VTA mtlfs in the proper schema.

Raw data is currently being received with the Express Lanes Api Receiver which writes the data to disk and triggers an update to the data served by the flask server.

The Flask server uses a combination of the dynamic data from the receiver and the static descriptive json data in our mtlfs repo to produce output for the api.

See an example with the discovery json or get the dynamic data directly at the toll status json.
